Speeification forming pzut of Letters Patent N0. 121,224, (lated November 21, 1871.

explained hereafter t0 need. preliminary deseripti0n, for rapidly 2u1d effectually punehing the eyelet-holes in whal: are commonly kuown as lzwed shoes, a-nd forintrodueing eyelets int0 the holes thus formed 211d there compressing them.

Figure 1, Sheet l, is a side view 0f 1ny shoepunching und eyeleting-maehine; Fig. 2, a front view 0f tl1e same; Fig. 3, a plan view; Fig. 4, a seetional view of the upper p0rti0n of the maehine, showing the punching anal work-feeding devices. Fig. 5, Sheet 2, is a vertical section of the machine 011 ehe lines l 2, Fig. 2, showing the devices f0r feeding 2md eompressing the eyelets; Fig. 6 and 7, enlarged views 0f tl1e eyelet-feeding deviees; and Figs. 8 aud 9, enlarged views of the work-feeding devices.

A represents tl1e frzune 0f tl1e machine, the uppe1 porti0n A 0f which is inclined, as best observecl in Fig. 5, f0r the reception of the eyelet-feeding devices, and in suitable be-arings a a in -the upper portion 0f the frame tun1s a drivingshaft; B, pr0 vided als 0ne end With a, fly wheel, G, 0nwhich is a crank-pin, b. Tl1e latteris 0011- neeted, by a rocl, b 130 a vibrating zum, b hung t0 the fixed frame, and operated, through the mediu1n 0f a conneeting-rod, c, 2u1d arm c, by a roek-shaft, D, arranged 110 cum in t-l1e lower portion 0f the frame, zmd provided at its front encl Will a treadle, F, by whieh, through the medium of the said roek-shafb a-11d the conneeting-rods ancl arms, the required rotary moti0n is imparted 130 the (lliVillg-Shflfl; B. (See Figs. 1 and 2.) The driving-shaft has at its inner end a eam, d, arranged to 0pemte a lever, d, hung t0 the fixed frame, 211d eonnected. ab its fr0nt end t0 a vertiea-lly sliding puneh, e, Fig. 4, whieh is forced downward by the said lever 011110 afixed p0st, e, for the purpose 0f cutting ehe eyelet-holes in the shoes, es hereafter 'deseriloed. The p0st e extends upward through a slot in, 211d serves t0 guide, the work-plate G, which slides upon a horizontal ledge, f, 0f the fixed frzune. A reciprocating motion is imparted t-o this sliding w0rkplate by a lever, g, the rear end. of which enters a gr0ove in a scroll-cam, h, hung o0 a sh0rt spin (11e, h parallel With the driving-shaft, 211d re' ceiving its motion from tl1e latter through 00ggeariug 71 (See Figs. 1,2,a11d 7.) 'lhe sliding w0rk-plate 0r table is 0f bhe box-like for1n best observed in Figs. 8 2md 9, 2u1d conains tl1e Workfeecling device, Wl1i0h eonsists 0f a rising und falling sermted plute, z, secured t0 or forming part 0f an arm, hung 130 0ne end of the b0x, and aeted 011 by a spring, Wl1i0h tends t0 0011- stantly foree the serrated plate upward thr0ugh a slot in the table, and above the face 0f oho latter. The arm z' has a recess, j, within whiel1 is bang a (10g, 7c, anal int0 which projects a pin, k, of the p0st e. Wl1en the table slides forward in the direetiou 0f the arrow, Fig. 8, the pin k asses through the lower p0rti0n 0f the recessj, aud the serrated feeding-plate projeets upward t0 its full exteut; but 011 11110 return movement 0f the table in the (lili0ll 0f the arrow in Fig. 9, the pin k mounts the in0lined dog k und passes 0ver the Same, and thus depresses tl1e sermtecl plate and is arm 130 a p0siti0i1 beneath the surface 0f the table.

The e yelet feeding and compressing deviees eure also oper'zuted by the treadle F in pr0per filme in respeco to the puneh und work-feeding table, es I will W proceed t0 describe: Theeyelets are eonbained within 2 b0x, H, seeured t0 01 forming pa-rt of a curved bar, J, which is adapted t0 zmd zumnged t0 slide in suit-able guides for1ned 011 tl1e inelined portion A 0f the frmne. (Figs. 5, 6, 2u1d 7.) In this eurved barthere is a channel f0r the eyelets, which are foreed into tl1esaid channel, through apertuteS in t-l1e side 0f ehe b0x, by m eans 0f a brush, l, the latter having a parbial rotary movement im1. arted t0 it, as tlie box and curvecl bar are reeiprocated by means of a 10d, m, Fig. 6, connected the fixed frame and t0 an arm 011 the spindle, t0 which alle brusl1 is attaeh ed. 'll1e required movement is imparted t0 tl1e box and eurved bar througl1 the medium 0f three levers, n, p, 2u1d q, and two conneetingrods, r 211d 'r, the lever n being attached directly t0 tl1e under side 0f the eurved bar, and being acted 0n loy a spring, whieh tends 130 move tl1e said bar in the direction 0f the arr0w, Fig'. 5, and the 1ever q extending beneath and being operated direetly by tl1e treadle F, the said lever hav1'ng a1: itsrear e1id a weight, n, which tends 130 hold its opposite end in contact with the treadle. 'Ihe eyeletcompressing devioe cousists of1zwo spring-punohes, s a11(l s, arrangecl one abowe the other, direooly 111 f10111; of the slidingwork-talole G, a11d 111 such a position also 13hat a be111; finge1 01 eyelet-holder, t, ab the lower e11d 0f the ourved and ohannelecl bar J may be 111- se1ted between 1311e1n. The lowermost punoh s is forcecl upwarcl ab he proper moment f0r 00111- pressing 1:11e eyelet by 13he lever q, to one arm of whieh 11:1s conneoted. The eyelet feeding ancl oompressing deviees oa11 be thrown 0ut of gear With 1;he work punohing and feeding meohanism by depressing the front e11d of the lever q so tl1a1: it may not be struck by the t1eadle, this bei11g effectecl by means of a latoh, u, 011 the fran1e oonneoted with the lever q by 13W0 oonneotingrods, 11 0 a11d a segmental lever, '0 The 111achine, as above desoribed, is inteuded eo simultaneously puneh 1;he eyelet-holes a1; regular distances apart 111 wha1: are 001111110111y known as laced shoes, and to introduoe th.e eyelets i1100 the holes tl1us punehecl anal 11here oompress them.

'Ihe operation is as follows: The box H is filled Wi11h eyelets, ancl the latter a1e b1ushed through 11he aper1mres 111 1;he side of 1;he said box 111115il the inelinecl ohannel of the ourved bar J is filled. (See Figs. 6 and 7.) A shoe is then 1aid and hold up0n the sliding work-tabl'e G by the attendant, W110 then ope1ates 1311e treaclle. Ab the firs1s desoent of 13he punoh e an eyelet-hole Will be 01113 in'1she shoe, a11d as s0o11 as the said punoh has ascended 1;he sliding table and i13s serrated plate Will move forward a given distanoe. carrying the work beneath a small roller, w, whieh holds it (l0W11 1:0 ohe tab1e. The punoh Will then again descencl, outting a seoond eyelethole, and the work-table Will 1110ve back 110 its original position, the serratecl plate being clepressed so as 11013 130 draw back the W0rk. 'Ihe puneh Will then asoend, and the work-table anal work Will loe again fed forwarcl preparatory to the pu11ohing of a third hole. As the work is thus fecl forward it will be oar1iecl between the pnnohes s and s, ancl over 1;he eyelet-holding fingert, an eyelet being droppecl from the la1ster onto the puneh s, so 15ha13 when ol1e latter is lifted shnultaneously With the deseending of the punoh t0 01113 a thi1'd hole the eyelet 011 t-he same may be oarriecl upward through 1:he first hole out in ehe shoe a11d oompressed over the same against the under side of the head x, 011t0 Whi0h the yielding punoh s is fixed. Prior 130 the lifting of the puneh s, however, ehe ourve l sliding bar J a11d i1;s finger t are withdrawn so as 11011 130 interfere with 1:he eompressing of the eyelet. When these several operations are compleued, and while the punohes still re1:ain their hold up011 the sl1oe, the sliding work-table Gr is clrawn back, after whioh the punohes are withdrawn, and 13110 ourved bar J a11d its finger t oarry another eyele1; d0w11 and drop 113 01110 the puneh s. Ihe work is the11 again fed forward, a11d a fourth hole is punohed a11d 1:he seconcl eyelet eompressecl, the punehed holes being iuvariably' brought opposite to the eyeleting-punohes, and the W01k being tl1us 0011- tinuecl With the greate'st rapiclity u111;1l 1;he desi1ed number of holes has been punohed and eyeletecl.

I claim l. The oombination of the sliding box G, 0211- rying Withil1 it a feeding dev1'oe, operating sub sta11tially as desoribed, the post e or its equiva lent, and the eutting and punohing clevioes, substantially as set forth.

2. The two Sets of punohes e e a11d s s, and the sliding platform G, so operated 111 respeot so eaoh other 13ha1; the punohes shall re111ai11 111 coutaot Wih ancl hold the W01k during the rearward movement of the sai l platforn1.
